No, I don't think that follows.
In the two cases discussed, I determined that the printers do PostScript
by just Web-searching for the product spec pages.

Add Printer, pick 'Generic' for Make. Pick your choice of any of the
Generic PostScript entries shown.
That's not very optimised -- and also you will in most cases find a good
entry by just taking the path of least resistance and picking your
printer's make and model -- or, better yet, using autodetect.
My original point was that you can supplement CUPS's default collection
of printer drivers by installing optional distro packages of those drivers,
and I'm sure that remains true for many distros. How you find and grab
those packages is pretty much distro-specific, though.
